Omron manual G7/F7/L7/E7 inverter PLC 371, Switch to select port 1 type of connected device

6. Communications port

Connects the PLC to a programming device (including programming consoles), host computer, or standard external device. Use a proper connecting cable (CPM2C-CN111, CS1W-CN114, CS1W-CN118, or CS1W-CN226).

Note: 1. A CQM1H-PRO01-E programming console can be connect- ed directly to the PLC.

2.A C200H-PRO27-E programming console can be connected directly to the PLC with a CS1W-CN224/CN624 connecting cable.

3.Use a CPM2C-CN111 or CS1W-CN114 connecting cable to connect to the communications port as a peripheral port. The communications port can be used simultaneously as both a peripheral port and RS-232C port by using the CPM2C- CN111 connecting cable.

4.Use a CPM2C-CN111, CS1W-CN118 or CS1W-CN226 con- necting cable to connect to the communications port as a RS- 232C port. The communications port can be used simulta- neously as both a peripheral port and RS-232C port by using the CPM2C-CN111 connecting cable

Note: The peripheral port and RS-422/485 port cannot be used simul-

taneously. When using the peripheral port disconnect any devices connected to the RS-422/485 port.

7. Communications switch

Note: The maximum line length is 500 m.

The peripheral port and RS-422/485 port cannot be used simul- taneously. When using the peripheral port disconnect any devices connected to the RS-422/485 port.

When using RS-485 communication, connect RDA- to SDA- and RDB+ to SDB+.

10. Terminating resistance switch

		Position	Termination
		OFF (right)	Disabled
ON	1	(default)
		ON (left)	Enabled

Set this switch to ON only for double-ended connection to a host link network.

Use special flat cable or VCTF cable for the transmission lines that con- nect the nodes in the CompoBus/S I/O Link. (Special flat cables and VCTF cables cannot be combined in the same system.)

Name	Model number	Specifications
Flat cable	XB1T-W10	4-core flat cable, 0.75 mm²
VCTF cable	---	2-core VCTF, 0.75 x 20
